When chasing the Israelites Pharaoh place the female horses ahead of the male horses. The males chased the females that ‘run away’ from them. When they came close to the Israelites, Pharaoh switch the leading females with the males because they are more daring and ready for war.
“וַיהוָה הֹלֵךְ לִפְנֵיהֶם יוֹמָם בְּעַמּוּד עָנָן, לַנְחֹתָם הַדֶּרֶךְ, וְלַיְלָה בְּעַמּוּד אֵשׁ, לְהָאִיר לָהֶם–לָלֶכֶת, יוֹמָם וָלָיְלָה”
“And YHVH was going before them in a pillar of cloud by day to lead them on the way, and in a pillar of fire by night to give them light, that they might travel by day and by night.”
“וַיִּסַּע מַלְאַךְ הָאֱלֹהִים, הַהֹלֵךְ לִפְנֵי מַחֲנֵה יִשְׂרָאֵל, וַיֵּלֶךְ, מֵאַחֲרֵיהֶם; וַיִּסַּע עַמּוּד הֶעָנָן, מִפְּנֵיהֶם, וַיַּעֲמֹד, מֵאַחֲרֵיהֶם”
“The angel of God, who had been going before the camp of Israel, moved and went behind them; and the pillar of cloud moved from before them and stood behind them.”
The above verses reveal how God protected the Israelites on the way to the Promised Land. God lead them with the pillar of fire at night and clouds of honor during the day. When the Egyptians came close, God moved the Shechinah from the front to Israelites to their back to make the fight by himself and destroy the Egyptians.
The verse (Exodus 14:19) that describes the move of the Shechina to protect the Israelites is the first verse of the three that construct the 72 names. It tells us about the root power of the 72 names.
